diameter of the sun is 1.392×10^9m, and the diameter of the earth is 1.275×10^7m. find the approximate ratio of the diameter of the sun to the diameter of the earth.
Answers
Answer:
Sun diameter= 1.392 X 10^9m = 1.4 X 10^9m(app.)
earth diameter= 1.275 X 10^7m
According to question:
sun:earth= (1.4 X 10^9m) / (1.275 X 10^7m)
= 1.4 X 10^2m / 1.275 m
=1.4 X 100 / 1.275
=109.752
= 110
Step-by-step explanation:
Diameter of Sun = 1.392×10⁹
This can also be written as:
Diameter of Sun = 139.2×10⁷
Diameter of Earth = 1.275×10⁷
Ratio of diameter of Sun to the diameter of Earth
= (139.2×10⁷)/(1.275×10⁷)
10⁷would be cancelled by 10⁷ easily and then it will be:
= 139.2/1.275
= 109/1 (approx.)
= 109:1 (approx.)
(Important Note: The answer is given in approximation as per the information given by you. The exact diameter of Sun and Earth could be something else and also exact ratio could be something else.
This can not be considered in scientific experiments related to space as this is not the exact value)
